Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] To address the issue of complex sealing unit structures in existing corrugated cardboard boxes, which negatively impact packaging efficiency during practical use, please refer to... Figure 1 - Figure 5 This embodiment provides the following technical solution:

[0024] This embodiment of a quick-sealing corrugated cardboard box includes a corrugated cardboard box shell 1. A horizontal strip 101 is fixedly installed at the middle of the upper end of the corrugated cardboard box shell 1. Outward folding plates 2 are provided on both sides of the horizontal strip 101. A movable folding part 103 is provided between the outward folding plates 2 and the horizontal strip 101. An integrally formed inner groove 106 is provided on both sides of the corrugated cardboard box shell 1. A sealing plate 201 is provided at one end of the outward folding plate 2. The sealing plate 201 is embedded in the inner groove 106 and fits against the corrugated cardboard box shell 1. The lower end of the encapsulation plate 201 is provided with two cardboard inserts 202. The upper end of the corrugated cardboard box shell 1 is connected and encapsulated by two symmetrical outward folding plates 2. The two outward folding plates 2 can be folded by the movable folding parts 103 on both sides of the horizontal strip 101 to realize the opening and closing. By the weight of the encapsulation plate 201 on one side of the outward folding plate 2, the outward folding plate 2 can be covered on the opening 108 to keep it closed. The cardboard inserts 202 are inserted into the encapsulation slot 107 for quick encapsulation.

[0025] The bottom of the inner groove 106 is provided with two integrally formed encapsulation slots 107, and the cardboard insert 202 extends through the encapsulation slots 107 into the interior of the corrugated cardboard box shell 1.

[0026] Furthermore, both sides of the interior of the corrugated carton shell 1 are provided with limiting baffles 109. The interior of the limiting baffles 109 is provided with an integrally formed inner bending groove 110. Two cardboard inserts 202 are embedded in the inner bending groove 110 and respectively abut against the limiting baffles 109 and the corrugated carton shell 1. The cardboard inserts 202 are folded through the inner bending groove 110 inside the limiting baffles 109 and bend upward under the pushing force to achieve fixation and prevent the sealing plate 201 from falling out of the inner groove 106. While sealing quickly, the sealing strength is maintained, which is conducive to improving packaging efficiency. The included angle between the outer folding plate 2 and the sealing plate 201 is set to ninety degrees. The sealing plate 201 abuts against the outside of the inner groove 106 and abuts against the corrugated carton shell 1.

[0027] Specifically, the upper end of the corrugated cardboard box shell 1 is connected and sealed by two symmetrical outward folding plates 2. The two outward folding plates 2 can be folded by the movable folding parts 103 on both sides of the horizontal strip 101, thereby realizing the opening and closing. By the weight of the sealing plate 201 on one side of the outward folding plate 2, the outward folding plate 2 can be covered on the opening 108 to keep it closed. The cardboard insert 202 is inserted into the sealing slot 107 for quick sealing. The cardboard insert 202 is folded by the inner bending groove 110 inside the limiting baffle 109 and bends upward under the push force to fix it and prevent the sealing plate 201 from falling out of the inner groove 106. While sealing quickly, the sealing strength is maintained, which is conducive to improving packaging efficiency.

[0028] To address the issues of complex sealing unit structures and cumbersome assembly / disassembly mechanisms in existing corrugated cardboard boxes during practical use, please refer to... Figure 1 - Figure 5 This embodiment provides the following technical solution:

[0029] In this embodiment, handles 104 are installed on both sides of the corrugated cardboard box shell 1. A fixing plate 105 is fixedly connected to the bottom of the handles 104. The fixing plate 105 is fixedly connected to the corrugated cardboard box shell 1 by buckles. The handles 104 facilitate handling without affecting the packaging structure, so as to adapt to transportation work.

[0030] It should be noted that the corrugated cardboard box shell 1 has an integrally formed opening 108 on both sides of its upper part. The outward folding plate 2 covers the upper end of the opening 108 and is closed and connected to the corrugated cardboard box shell 1. The opening 108 is used for material storage. The reinforcing cardboard 102 is fixedly connected to both sides of the corrugated cardboard box shell 1. The reinforcing cardboard 102 is fixedly connected to the horizontal strip 101. After the outward folding plate 2 is sealed on the upper end of the corrugated cardboard box shell 1, when disassembly is required, the cardboard insert 202 is pulled out. After the cardboard insert 202 is removed from the corrugated cardboard box shell 1, the outward folding plate 2 is opened to carry out efficient disassembly and assembly, which is conducive to continuous use and easy to operate.

[0031] Specifically, after the outer folding plate 2 is sealed on the upper end of the corrugated cardboard box shell 1, when disassembly is required, the cardboard insert 202 is pulled out. After the cardboard insert 202 is removed from the corrugated cardboard box shell 1, the outer folding plate 2 is flipped open to carry out efficient disassembly and assembly work. This is conducive to continuous use and easy to operate. The handle 104 makes it easy to carry without affecting the sealing structure, so as to adapt to transportation work.

[0032] Working principle: In use, the two outward folding plates 2 can be folded through the movable folding parts 103 on both sides of the horizontal strip 101 to achieve opening and closing. The outer folding plate 2 can be covered on the opening 108 by the weight of the sealing plate 201 on one side of the outer folding plate 2, keeping it closed. The cardboard insert 202 is inserted into the sealing slot 107 for quick sealing. The cardboard insert 202 is folded through the inner curved groove 110 inside the limiting baffle 109 and bends upward under the push force to fix it and prevent the sealing plate 201 from falling out of the inner groove 106. While sealing quickly, the sealing strength is maintained, which helps to improve packaging efficiency. The handle 104 makes it easy to carry without affecting the sealing structure, so as to adapt to transportation. When disassembly is required, the cardboard insert 202 is pulled out. After the cardboard insert 202 is removed from the corrugated carton shell 1, the outer folding plate 2 is opened for efficient disassembly and assembly, which is conducive to continuous use and easy to operate.
